CHECKING AND MAINTAINING FILTER
Maintain the filter by checking it frequently. Depending on air quality conditions, you may need to
replace it more frequently. Vacuum the carbon filter layer as needed to remove loose debris and
dust and to help prolong the life of your filter. To check the status of the filter, peel back the carbon
layer to expose the pleated filter. If the filter is no longer white and is covered in grey dust/dirt, it
should be replaced.
IMPORTANT: Do NOT try to wash and re-use the Combination Filter.
IMPORTANT: Use Guardian Technologies GENUINE Replacement Parts only.
